Mark Carney declared Shadow Chancellor Rachel Reeves a “serious economist” in a surprise video message after her conference speech.
The ex-Governor said: “She began her career at the Bank of England, so she understands the big picture.
“But, crucially she understands the economics of work, of place and family. And, look, it is beyond time we put her energy and ideas into action.”
Since leaving Threadneedle Street in 2020 Mr Carney has been very critical of Brexit, blaming it for rising inflation.
Ms Reeves’ spokesman was quick to stress he has no formal advisory role in Labour and her own personal views on Brexit are well known.
The spokesman dismissed concerns that Mr Carney’s support risked “politicising” the Bank of England, saying the Shadow Chancellor was “proud” to have his backing.
Mr Carney is the latest ex-public official to either directly or indirectly back Labour, with career civil servant Sue Gray memorably joined as Sir Keir Starmer’s top aide.
Ms Reeves’ speech promised to “rebuild Britain” by staying laser-focused on economic growth.
She confirmed her intention to tax private schools 20 per cent VAT in her first budget if elected.
And the Labour aspiring chancellor also unveiled plans to clampdown on waste such as ministers’ use of private jets – although does not know how much it would save.
Chancellor Jeremy Hunt said one glaring omission was inflation, which Ms Reeves failed to name-check.
He said: “Oops…when the biggest single issue for the economy is inflation it doesn’t get ONE mention from the Shadow Chancellor?
“Because adding £28 bn a year to borrowing will push it up – meaning higher mortgages, higher debt interest and lower growth.”
